The number of new listings on the website in July increased to 9,163, from 8,524 in June, a rise of 639 or 7.5%.
"The number of listings should be seen as indicative of the usual seasonal cycle," Realestate.co.nz marketing manager Paul McKenzie said.
"Every year we see a surge in the number of properties in the market when spring comes around and there is every reason to expect that the same will happen in August and September this year."
Realstate.co.nz's average asking prices are based on a truncated mean, which excludes the top and bottom 10% of prices.
